[Mp4-tech] Question regarding slice groups

[Nitin PAI]

Hi,
I want to know the significance of introducing slice groups.  I understand
that the slices are needed for error resilience.  Does slice groups serve
only the need of grouping the slices in raster order or ease of specifiying
the slice group map?  Or is there any other things like a slice group is an
independent decodable entity ( i mean the motion vectors should be
constrained to lie inside the slice group only?)
Thanks,
Nitin
